The correct answer is the following.
Although there is no excerpt attached or another kind of reference, we can say that the question refers to the story of Frankenstein, written by English writer Mary Shelley in 1818.
In this story, power corrupts in that the monster tries to create revenge against Victor. The monster or the creature knows that it was created in such a way by Victor that it won't be able to fit into society. The creature can't control its hunger for killing people who are close to Victor.
That is why, when today people can control their actions it is said that "they cannot control the monster inside."
The answer is: A. to point out details the character would not notice.
The first-person point of view is a literary device that allows readers to get to know that character's thoughts, feelings and motives. Because the narrator refers to himself with words like <em>I, me, my </em>and <em>mine</em>, the story is seen through his or her eyes. As a consequence, it is not impartial and it may suggest features which are unknown or unnoticeable to the narrator. For example, they might not realize they have a psychological condition.
